<pre>A few test262 tests fail after:
<<a href="https://webkit.org/b/163338">https://webkit.org/b/163338</a>> Array.prototype.slice should not modify frozen objects
<<a href="http://trac.webkit.org/r207226">http://trac.webkit.org/r207226</a>>
Steps to Reproduce:
1. Check JSTests/test262.yaml expectations for the above file paths (if they are marked as :fail)
2. $ run-jsc-stress-tests JSTests/test262.yaml
Notes:
- Not sure if these are progressions, but since the tests themselves don't seem to mention freezing anything it seems unexpected.
- If this is an actual failure the expectations can be changed to :failDueToOutdatedOrBadTest
